    Hi, I have a PSP Street and I'm having this issue with the Home button: it's like it's always pressed.
    At the beginning I thought to replace the front bar but I noticed the I have the same issue even if I remove the bar from the motherboard.
    This issue prevent me from using a permanent firmware because if you power on the psp pressing the home button it boots up with the OFW instead of the CFW.
    Also, if I start an emulator or any other game it keeps opening the menu because it's mapped to the home button.
    In another thread @Foxi4 suggested to disassemble the unit and give it a good scrub because the HOME trace may be shorting to ground somewhere.
    I'll give it a try and post here the result so if anyone else will have the same issue may find a solution.
    If someone's tips about how to check for possible shorting to ground or how to clean the motherboard avoiding to break some stuff I'll be glad to hear your opinion.
    Thank in advance.

    Solved removing the motherboard and giving a good scrub.

    Glad to hear that my advice worked! Dust likes to get conductive after long-term storage, and there's moisture at play too - it's why you don't connect vintage equipment to the mains before a thorough inspection. Another one saved, good job, man!

    I forgot to mention that removing the battery cable I damaged the motherboard because the three pins were to weak :wacko:
    So now I can only play plugged with the charger :psp:

    Big yikes! Well, I don't know if it helps, but with a little care you *can* hardwire the battery to the mobo, or do the full monty and replace the whole connector as long as you haven't ripped the traces off the PCB. If you have, you can trace them back to the next closest component and solder to that pad instead. On the bright side... it works now! :yaypsp:

    Do you know where I'd find the TA-097 schematic? I was able to find the one for another psp model but not the one for the Street.

    Never worked on the Street myself, and I can't say I've ever used a schematic for a repair either - I just track the trace with a meter. At the end of the day it's just three traces - positive, negative and sense. I'd be surprised if the general area of the connector wasn't similar to the previous models. If I were to find a schematic, between Google-fu and here, I'd try Acid Mods or other websites dedicated strictly to hardware.

    Should I weld on those three point? Because the traces are gone.

    Yeah, you should scratch off the green paint and connect to another point of the track
    (might be problematic for the thermal sensor pin, though I don't remember if it's actually used)
